What is the probability of getting an even number in a single throw of a dice?

Model Answer

Mathematical Probability Solution:

  • Sample Space for rolling a fair die: S = {1, 2, 3, 4, 5, 6} ⇒ n(S) = 6
  • Favorable outcomes for an even number: E = {2, 4, 6} ⇒ n(E) = 3
  • Probability: P(E) = n(E) / n(S) = 3 / 6 = 1 / 2 = 0.5

Answer: The probability is 1/2.

हिंदी में प्रश्न एवं आदर्श उत्तर

एक पासे को एक बार फेंकने पर, एक सम संख्या आने की प्रायिकता क्या होगी?

हल:

  • एक पासे को फेंकने पर कुल संभावित परिणाम = S = {1, 2, 3, 4, 5, 6} ⇒ n(S) = 6
  • सम संख्याएँ आने के अनुकूल परिणाम = E = {2, 4, 6} ⇒ n(E) = 3
  • प्रायिकता = P(E) = n(E) / n(S) = 3 / 6 = 1 / 2 = 0.5

उत्तर: सम संख्या आने की प्रायिकता 1/2 (50%) है।
